vSIPECIFICA'IION rforming part of Letters Patent No. 473,525, dated April 26, 1892.

Serial No. l05,281. (No model.)

To all whom t may concern.-

vBe it known that I, JOSEPH RIDGE, of Ohicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Vehicle-I/Vheels, of which the following is a full and complete specification.

The purpose of my invention is to provide against vibration of a vehicle over unevensurface roadways by the application of peripheral springs to the wheels.

I am aware that tubular rubber tires, with and without iniiation, are in use for the purpose, but attended in the one form with partial success and in the other with lack ofsatisfactory practicability.

To obviate the difficulties found in the use of tubular rubber, I provide springs of metal or of other material possessing the required strength and exible elasticity, a series of which are superimposed throughout the circumference of a Wheel, as hereinafter set forth, whereby all the desired elasticity is obtained with durability equal to a Wheel of ordinary construction.

For the purpose of description reference is had to the accompanying drawings, in which- Figure l is a side view of a peripheral section of a wheel, the rim portion being shown in longitudinal section. Fig. 2 is a top view of the section, the tire being omitted. Fig. 3 is an end view showing the rim in full width. Fig. 4 is a detail showing one of the springs.

The rim A is of the usual construction used for velocipedes-t` e., semicircular in crosssection-Whereby in the ordinary wheel it is adapted to retain the cylindrical rubber tire. This form of rim I have retained, as a channel serves a purpose hereinafter named, in connection with springs used in my improvement, that makes it desirable.

Attached to the rim are shown the outer portions of spokes b. The series of springs by Which the desired elasticity is obtained are lettered ce. The springs are, as I believe, for velocipedes, preferably constructed of steel wire tempered,-each of` a single piece, as affording simplicity, lightness, and neatness, though for vehicles of aheavierkind iiat or leaf springs might be preferable, especially so should it be desirable to have the springs also serve as a tire. The doubledv ends of the springs are respectively secured to the bottom of the rim-channel by means of screwethreaded staples and nuts c, holes being drilled through the middle portion of the rim to receive the ends of the staples. The outer ends of each spring rest upon an adjacent spring about midway ofthe latter throughoutthe series. The primary metallic loops d, having a semicircular central portion as a tire-support, are so formed that each of its ends is adapted to loosely admit two thicknesses of wire, through which the branches of one spring and the ends of the superincumbent spring are respectively inserted, thus holding said springs in position with relation to each other and to the whole spring structure, and at the same time permitting a longitudinal movement of one spring upon another, which flexion of lthe springs under pressure slightly produces. Loops d', intermediate between the loops d, are provided on each spring to serve in supporting the tire. `The tendency of the loops to recede from their proper position on the springs, caused by the rotation of the wheel under pressure, necessitates fastening. This, in order not to interfere with the flexion of the springs, I accomplish by means of tie-straps e, in number equal to that of the springs, constructed from flexible strips of metal. These tie-straps, respectively, have one of their ends secured to the wheel-rim by means of staples c. The outer ends of the tie-straps are respectively secured by rivets to a pair of loops d d. The tie-straps also incidentally serve to bridge alternate spaces between loops as additional support for the tire. between loops may be partially or wholly bridged by extensions from the loops, as indicated at t, which extensions should be curved in cross-section to better withstand pressure. cured to both such loops would interfere with the action of the springs.

B represents the cylindrical rubber tire, which should have such tensile elasticity as to be readily restored when flexion occurs coincident with compression of the springs.

The doubled ends of springs a iit closely in the rim-channel, which, in connection with loops d, serve to prevent lateral play or displacement of the springs.

The method of fastening by staples makes The remaining spaces It is obvious that connections se-` shaping the doubled ends of the springs that the portions thereof enteringA the channel when inserted perpendicular to a tangent of the rim-curve tit closely. Thus, the spring being slightly Wider from the rim outward, when it is brought to its proper inclined position a contact is formed between spring and .rim that acts partially as a fulcru m, and thereby reduces the Iiexibility of the spring, thus adapting the cushioning qualities of the series to sustain greater weight. This may be further moditied by tightening or loosening the staple-nuts.

The arrow. indicates the direction in which the wheel should rotate, that the springs may have their desired action.

Having thus fully described my said invention, what I claim, and desire to secure by Letters Patent, is

l. In a vehicle-wheel exterior to and secured to its rim, a series of overlappingsprin gs, the outer ends thereof being free and successively supported one by another, whereby a contin nous cushion is formed about theperiphery of said Wheel, substantially as specified.

2. In combination with rim A, the series of Wire springs ct, having their free ends joined by loops d, substantially as described.

3. In combination with rim A, the springs a, and fiexible tire B, substantially as specified.
